The pumping fluid is FUEL OIL with viscosity of 940 CP. The required power will increase because of the efficiency correction factor of 0.6! Is it usual to use centrifugal pumps for such viscose fluid and mentioned condition? On the other hand, many operational problems will be raised during...

Hello BigInch agin, Thanks so much for your kindd hepls, I have problem with the pump selection, let me explain to you, Actually for pump type selection I used Exxon Mobil Corporation guids. They mentioned for viscosity over 600 CP centrifugal pumps are not suitable, then I used screw pumps...

With the viscosity of 95 CP (Centi pose)? It realy will be appicable?

Thanks.

As I mentioned before, the Min./Normal/Max. visscosity will be 57/300/950 CP respectively for Fuel oils with capacity of 1250m3/hr and discharge pressure of 17 barg. Also the design case will be maximum viscosity(950 CP). The pumps will be used in Tank farms to transport the products into the...

Thanks Biginch, The problem is that there arent any avilable utility at our site. The site will be new Tank farm and there are much process pumps to pumpig the hydrocarbin into the ships. As I mentoned there are not any source of air, cooling water,...for this meen and also manufacturers...

Does anyone know when screw pumps are used. In the project we had lots of hydrocarbon like Naphtha, gas oil, gasoline…. For Fuel oil with the viscosity of 950 CP and flow rate of 1250m3/hr, I used twin screw pumps which now the client ask us to use the centrifugal ones or explain whay...

Dear Sir/Madam, Would you please explain when dual mechanical seals are used? I konw fr the hazardous services (toid,...)dual mechanical seal are used. We have some centrifugal API 610 pumps with hydrocarbon fluid (Aromatic Feed, Naphtha,…) with discharge pressure 13 barg. Some famous...

Dear Sir/Madam, Would you please explain the physical meaning and effect of the Nss? I have found that it is related to pump performance and calculated for BEF of the maximum impeller diameter... Who it connect duty point to the BEP of maximum impeller diameter? Different reference present...
